Web 2.0
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Web 2.0, a phrase coined by O'Reilly Media in 2004, refers to a
supposed second-generation of Internet-based services such as
social networking sites, wikis, communication tools, and
folksonomies that let people collaborate and share information
online in previously unavailable ways. O'Reilly Media, in
collaboration with MediaLive International, used the phrase as a
title for a series of conferences and since then it has become a
popular (though ill-defined and often criticized) buzzword amongst
certain technical and marketing communities.
